Food is nourishment, fuel, comfort, our daily bread. It helps us grow, brings us health, draws people together, can be simple or pretentious. Yet one man’s meat is another man’s poison. Peanut butter is harmless to most children, but can be deadly to others. Between these extremes of sustenance and severe allergies are many shades of grey, and these are the food sensitivities and intolerances. When someone has a food allergy, whether it’s severe or mild, the reaction is immediate and observable, such as hives, swelling, trouble breathing or vomiting. What many of us don’t realize is that we can be reacting to food days later and never make the connection between our symptoms and what we have eaten. The big question is why do we develop these reactions to foods we’ve been eating all our lives? Dr. Clare Westmacott, MD brings an integrated approach to his medical practice and often has his patients undergo food sensitivity testing because we can't be healthy when food becomes the enemy.
